Hi,
i'd love to bump this one. I think this is the only remaining blocker issue for ZTS usage on PHP 7.2. Using the incomplete patch from nikic fixes all crash related issues for my use case. (I know the memory leak problems) It would be awesome if we could get this properly fixed and tested until the 7.2 release. I would love to help - but i have no idea where to start.
Would it help if i could reproduce the issue with the pthreads extension? (https://github.com/krakjoe/pthreads)? It should be affected aswell.
Thanks a lot in advance!
